FCC Compliance and Advisory Statement This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and A printed version of this document is an uncontrolled copy 2020 Unex Technology Corporation Company Confidential 3/11 Doc. No: Unex-HDG-20-001
(2) This device must accept any interference received, including interference that may cause undesired operation. 4.1. Information for the OEMs and Integrators The following statement must be included with all versions of this document supplied to an OEM or integrator, but should not be distributed to the end user. 1) This device is intended for OEM integrators only. 2) Please see the full Grant of Equipment document for other restrictions. 4.2. Manual Information to the End User The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the users manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warming as shown in this manual. 4.3. Federal Communications Commission Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. A printed version of this document is an uncontrolled copy 2020 Unex Technology Corporation Company Confidential 4/11 Doc. No: Unex-HDG-20-001 Consult the dealer or an experienced radio/ TV technician for help. CAUTION:
Any changes or modications not expressly approved by the grantee of this device could void the users authority to operate the equipment. 4.4. Modular approval RF Exposure This equipment must be installed and operated in accordance with provided instructions and the antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. End-users and installers must be provide with antenna installation instructions and consider removing the no-
collocation statement. 4.5. Labelling Requirements for the Host device The host device shall be properly labelled to identify the modules within the host device. The certification label of the module shall be clearly visible at all times when installed in the host device, otherwise the host device must be labelled to display the FCC ID and IC of the module, preceded by the words "Contains transmitter module", or the word "Contains", or similar wording expressing the same meaning, as follows:

Receptacle connectors are compatible with I-PEX MHF I 20279-001E-03 or HIROSE U.FL-R-SMT-1(10). For more information about mating connectors, visit the website https://www.i-pex.com/Products/detail/129 or http://www.hirose-connectors.com/ for more detail. V2X0 ANT MHF I, 50 V2X1 ANT MHF I, 50 Figure 3: Antenna connectors The antenna connection is one of the most important aspect in the full product design as it strongly affects the RF performance. Connecting cables between the module and the antenna must have 50 impedance. If the impedance of the module is mismatched, RF performance will be reduced significantly. Please be careful when extracting the antenna cable from the VTX-301. Extracting the connector by pulling the cable may cause damage on the antenna plug assembly. It is recommended to extract the cable using extraction tool like I-PEX 90192-001 or HIROSE U.FL-LP-N-2. A printed version of this document is an uncontrolled copy 2020 Unex Technology Corporation Company Confidential 7/11 Doc. No: Unex-HDG-20-001 Figure 4: Antenna cable extraction tool 7.1.2. Operating Frequency VTX-301 can transmit/receive in U-NII-4 band (5850-5925 MHz). There are 7 available channels (172, 174, 176, 178, 180, 182, and 184) with 10 MHz bandwidth. If using U-NII-4 band is not allowed by local authorities, U-NII-3 (5725-5850 MHz) can be used as an alternative option. 7.2. Pinout Please note that the pinout listed here is seen from the VTX-301 side. For designing a system board interface, the input and output direction must be reversed. Typical internal PU/PD resistor is 30K-70K .

Applying a soft silicone thermally conductive pad to fill the air gap between VTX-301 and its system board could help disperse heat generated by the VTX-301 to the system board. It is recommended to keep continuous large copper pour area on the system PCB underneath the VTX-301, better with exposed bare copper especially directly under the CPU. The distance between system board and CPU top surface is 3.7mm. Recommended size of thermally conductive pad: 16x16x4mm. Thermally Conductive Pad Area 16x16x4mm Figure 5: Recommended Thermally Conductive Pad Area 7.4. Component Keep Out Area In order to avoid interference with VTX-301, the system board side component height underneath the VTX-301 should not exceed 3.0mm.
